I watched this video, and it shows how this works for all illnesses and even prevention. If everyone did this, they'd be as well as me. But it's not enough to just do intestinal remodeling; you need lifestyle changes: fresh air, physical activity, proper sleep, a balanced diet, temperance, spirituality, water, sun exposure, confidence. You also need someone to listen to you. The books I used to sell door-to-door talk about this; all my training is on this. I even lived in Okinawa to see how it worked in practice. But anyway, the obvious needs to be said, and there are people who charge fortunes to do what grandmothers already did.
